摘要: 为了研究炭基复混肥料(炭基肥)对水稻氮磷钾吸收及产量影响,以杂交水稻‘株两优819’为试验材料,于2014年和2015年采用大田随机区组试验。结果表明:2014年氮肥、磷肥、钾肥利用率分别比普通肥提高了5.6%,4.3%和7.6%。2015年氮肥、磷肥、钾肥利用率分别比普通肥提高了6.3%,6%和8.5%。炭基肥处理在2014年和2015年的水稻产量都分别高于普通肥处理1.75%和1.41%。炭基肥对氮磷钾肥利用率的提高顺序为磷肥>钾肥>氮肥。总之,炭基肥能提高土壤中的氮磷钾的生物有效性,提高肥料的利用率,从而提高产量。

Abstract: In order to study the effect of carbon-based compound fertilizer (carbon-based fertilizer) on nitrogen(N), phosphorus(P) and potassium(K) absorption and yield, taking hybrid rice ‘Zhuliangyou 819’ as the experimental material, we set up field experiments using randomized block design in 2014 and 2015. The results showed that the utilization ratio of nitrogen fertilizer, phosphate fertilizer and potassium fertilizer under carbon-based fertilizer treatments increased by 5.6%, 4.3% and 7.6%, respectively, compared with that under ordinary fertilizer treatment in 2014. The utilization ratio of nitrogen fertilizer, phosphate fertilizer and potassium fertilizer under carbon-based fertilizer treatments increased by 6.3%, 6% and 8.5% respectively, compared with that under ordinary fertilizer treatment in 2015. Carbon-based fertilizer treatments increased the rice yield by 1.75% in 2014 and 1.41% in 2015, respectively, in comparing with ordinary fertilizer treatment. The improved fertilizer utilization order of carbon-based compound fertilizer was P fertilizer>K fertilizer>N fertilizer. In conclusion, carbon-based compound fertilizer can improve bioavailability of N, P and K, and rice fertilizer utilization, thus to enhance rice yield.
